A short course in quantum information theory an approach by Lajos Diosi

This brief and concise primer takes the vantage element of theoretical physics and the cohesion of physics. It units out to strip the burgeoning box of quantum details technological know-how to its fundamentals through linking it to common options in physics. an in depth lecture instead of a complete textbook, this quantity is predicated on classes added over a number of years to complex undergraduate and starting graduate scholars, yet primarily it addresses an individual with a operating wisdom of uncomplicated quantum physics. Readers will locate those lectures a so much enough access aspect for theoretical reports during this box.

During this remarkably illustrative and carefully available examine some of the most exciting frontiers in technological know-how and desktops, award-winning ny instances author George Johnson unearths the attention-grabbing global of quantum computing—the holy grail of great desktops the place the computing energy of unmarried atoms is harnassed to create machines able to nearly incredible calculations within the blink of a watch.

The textbook covers the historical past conception of varied results mentioned from first ideas, as in actual fact as attainable, to introduce scholars to the most principles of quantum physics and to coach the elemental mathematical equipment and strategies utilized in the fields of complicated quantum physics, atomic physics, laser physics, nanotechnology, quantum chemistry, and theoretical arithmetic.
